Desalination plants are becoming more common in places which have experienced ____a. an influx of refugeesb. damaging earthquakesc. mass deforestationd. shortages of fresh water
Answer:
Shortages of fresh water
Explanation:
Desalination plants are becoming more common in places which have experienced shortages of fresh water. Desalination is a process that removes salt and other minerals from seawater, making it safe to drink. It is often used in coastal areas where there is a lack of freshwater resources or where the quality of available freshwater is poor.
Desalination plants can help to address water shortages by providing a reliable source of clean, fresh water. However, they can be expensive to build and operate and may have negative environmental impacts, such as the release of brine (a highly salty byproduct) into the ocean.

human chorionic gonadotropin helps to maintain the corpus luteum for the entire gestational period. t/f
Human chorionic gonadotropin is mostly produced by the syncytiotrophoblastic cells of the placenta during pregnancy. In the corpus luteum, the hormone stimulates the generation of progesterone.
What function does the corpus luteum serve?
The corpus luteum's function is to make your uterus a healthy environment for a fetus to develop, even though it is located inside your ovaries. It causes the production of the progesterone hormone, which gets your uterus ready for conception. Your corpus luteum disappears once it is no longer required for the production of progesterone.
What transpires to the corpus luteum in the absence of pregnancy?
If the egg is not fertilized, the corpus luteum undergoes its alternative fate. After ceasing to secrete progesterone, it will deteriorate and become a corpus albicans. This degradation typically takes place around

Why does it take 10 times more energy to grow a kilogram of beef than a kilogram of wheat? Wheat weighs less. Cattle eat only 10 percent of their body weight. Only 10 percent of wheat is digestible. Cattle only integrate 10 percent of their food into biomass.
Cattle only integrate 10 percent of their food into biomass. This is the reason why it takes 10 times more energy to grow a kilogram of beef than a kilogram of wheat.
Biomass contains chemical energy from the sun that has been stored. Photosynthesis is the process through which plants generate biomass. Biomass can be directly burnt for heat or transformed to renewable liquid and gaseous fuels via a variety of processes. Biomass encompasses both above- and belowground plant tissues, such as leaves, twigs, branches, and boles, as well as tree roots and grass rhizomes.
Biomass can be burned directly to provide heat, turned directly to electricity, or processed into biofuel (indirect). Biomass may be converted into energy through thermal conversion. Thermal conversion is the process of heating biomass feedstock to burn, dehydrate, or stabilise it. Methane generation is the biological process that converts animal waste into energy.

what is the outcome of a mutation within an intron with regard to the ultimate protein that will form from this sequence?
The outcome of a mutation within an intron with regard to the ultimate protein that will form from this sequence will be that a) the protein sequence will not be affected.
In the field of biology, introns can be described as the regions that are cut off from the mRNA before translation. The introns are not known to take any part in the protein sequence and hence are not included in the protein synthesis. The introns have no role in the formation of proteins. The exons of the mRNA are the only regions that code for the protein.
Hence, if such a scenario occurs, that a mutation is caused in the intron region, then this will have no effect on the protein sequence because introns have no role in the formation of proteins. Proteins are formed from the exon regions only.
Although a part of your question is missing, you might be referring to this question:

No, a change to a G would not result in a change in gene expression as the underlined C is a non-coding nucleotide and does not have any effect on gene expression.
Non-coding DNA corresponds to the portion of an organism's genome that does not code for amino acids, the building blocks of proteins. Some noncoding DNA sequences are known to play functional roles such as regulation of gene expression, whereas other regions of noncoding DNA have no known function. Other regions of non-coding DNA are important for protein assembly. By altering one of these regions, a variant (also known as a mutation) in the noncoding DNA can turn on the gene, causing the protein to be produced in the wrong place or at the wrong time. There are two types of SNPs in the coding region.Synonymous and non-synonymous SNPs. Synonymous SNPs do not affect the protein sequence, whereas non-synonymous SNPs change the amino acid sequence of the protein.

the phenotype of offspring would most likely be influenced by mutations during which biological process within the parent?
Answer:
Meiosis.
Explanation:
Meiosis is, by definition, "A special form of cell division in which each daughter cell receives half the amount of DNA as the parent cell", which is useful for mating and trait inheritance. For example, humans have haploid sperm and egg cells, which allows the resulting offspring to be diploid upon fusing of the two. Mitosis cannot be responsible for this, as in accord with what we know, DNA flows unidirectionally, with somatic cells not contributing to inheritance.
This could only mean that a mutation (e.g. Point, deletion, insertion, etc.) in the process of meiosis can cause changes in offspring phenotype.

Large air tubes leading from the trachea to the lungs which convey air to and from the lungs; consist of primary, secondary or tertiary and right and left bronchioles. The above statement is True.
The trachea splits into the right and left principal bronchi at the mediastinum at the level of the fifth thoracic vertebra. The bronchi split off into progressively smaller channels before coming to an end in tiny air sacs known as alveoli.
The primary bronchi's cartilage and mucous membrane resemble those of the trachea. The amount of hyaline cartilage in the walls reduces as the bronchial tree branches out until it is completely gone in the smallest bronchioles.
